[PATCH 5.4.y 2/4] dm table: fix partial completion iterate_devices based device capability checks

[Jeffle Xu <jefflexu@linux.alibaba.com>]

Similar to commit a4c8dd9c2d09 ("dm table: fix iterate_devices based
device capability checks"), fix partial completion capability check and
invert logic of the corresponding iterate_devices_callout_fn so that all
devices' partial completion capabilities are properly checked.

Fixes: 22c11858e800 ("dm: introduce DM_TYPE_NVME_BIO_BASED")
